Jakub,
    Can you check what --save-temps produces for g++.dg/tree-prof/partition1.C
in partition1.s on linux? Does it produce two sets of global statements as
well?

grep __Z3bari.eh partition1.S
.globl __Z3bari.eh
__Z3bari.eh:
.globl __Z3bari.eh
__Z3bari.eh:

If so, is this by design or is it a gcc bug which binutils tolerates.

Linux doesn't have __Z3bari.eh at all.

Oddly, if I build gcc trunk on x86_64 Fedora 10 with CPPFLAGS set to -fPIC and
run the testsuite with -fPIC, I don't see the .eh symbols...

grep globl partition1.s
.globl _ZN1AC2Ev

.globl _ZN1AD1Ev
.globl _Z3bari

.globl l

compared to x86_64-apple-darwin10...

[mrs at apple dot com]

------- Comment #10 from mrs at apple dot com  2009-09-30 20:54 -------
When targeting darwin10, the .eh symbols don't have to be generated anymore. 
They are from darwin.c, darwin_emit_unwind_label.

 if (darwin_macosx_version_min
      && strverscmp (darwin_macosx_version_min, "10.6") >= 0)

can be used, and the entirety of the routine can be avoided.  That said, this
is a bug somewhere, it can be found by binary searching the testcase on the
compiler sources until the change that dupped these is found.  I don't believe
it has always been broken.  Or, you can just put a breakpoint on this routine,
and when the second one is hit, find a variable that is different that the
first time it is hit, and pass that as a parameter and the bail out, just like
! for_eh.

Mike,
     I am a fuzzy on the best way to avoid darwin_emit_unwind_label since it is
assigned to a define in darwin.h. The only thing that makes sense to me is...

     return;

   lab = concat (IDENTIFIER_POINTER (DECL_ASSEMBLER_NAME (decl)), ".eh", NULL);

Does that seem reasonable?

------- Comment #12 from jakub at gcc dot gnu dot org  2009-09-30 22:46 -------
It is unclear what those labels are good for, but if darwin is to support
hot/cold partitioning and FDEs covering it, the emit unwind_label hook (which
is apparently darwin specific only) should be passed also the SECOND variable
and create different label name for the second FDE for the same function (if
function starts in hot section, then the second one is covering the cold
section, and vice versa).
The patch in #c11 would just mean you'd keep older versions broken.

Actually, the patch in Comment 11 leaves two of the original failures...

FAIL: g++.dg/tree-prof/partition1.C compilation,  -g  -fprofile-use
FAIL: g++.dg/tree-prof/partition1.C compilation,  -O3 -g  -fprofile-use

These remaining failing test cases are both accompanied by the numerous
warnings of the form...

ld: warning: can't add line info to anonymous symbol anon-func-0xF40 from
/var/tmp//ccwuqn0i.o

and

output is:
ld: warning: can't add line info to anonymous symbol anon-func-0xF40 from

Jakub,
   If you could propose a patch to the darwin_emit_unwind_label subroutine in
gcc/config/darwin.c to implement the changes you propose in Comment 12, I would
be happy to test it on darwin9/darwin10. I'm out of my depth to try to
implement that cleanly myself.

Yeah, the patch in #11 is about the right for half the problem (darwin10), if
it weren't for ld's warning message.  I don't know quite why it is doing that,
so guess we'll just have to nix that idea.  So, the next best thing would be to
just turn off hot/cold partitioning for darwin.  In override_option in
darwin.c, just do hot_cold = 0.

   It looks like this problem isn't strictly target specific (although we are
the only target currently impacted). If TARGET_ASM_EMIT_UNWIND_LABEL as defined
needs to support passing SECOND, both the default_emit_unwind_label() and
darwin_emit_unwind_label() prototypes would have to be revised to support this
additional variable as well as any place they are called from to properly
support hot/cold partitioning.

Won't disabling hot/cold partitioning for darwin potentially degrade the code
generation at -O3 or is this issue limited to -freorder-blocks-and-partition
only?

flag_reorder_blocks_and_partition was the complete name of the variable last I
looked.  If flag_unwind_tables is true and this variable is true, that's the

        label instead of LLSDA if it is true.
        (dwarf2out_begin_prologue, dwarf2out_switch_text_section): Adjust
        callers.
        * except.c (add_call_site, dw2_size_of_call_site_table): Add
        SECTION argument.  Use it as index into crtl->eh.call_site_record
        array.
        (dw2_output_call_site_table): Likewise.  Add CS_FORMAT argument,
        use it to determine how to print table entries instead of using
        #ifdef HAVE_AS_LEB128.  For SECTION > 0 use hot resp. cold
        label instead of normal begin label as base.
        (sjlj_assign_call_site_values): Adjust add_call_site caller.
        (convert_to_eh_region_ranges): When doing hot/cold partitioning,
        ensure no EH range spans between sections and that landing pads
        are always in the corresponding section.
        (sjlj_size_of_call_site_table, sjlj_output_call_site_table): Adjust
        for crtl->eh.call_site_record being an array rather than scalar.
        (output_one_function_exception_table): New function, copied
        from output_function_exception_table.  Adjust
        dw2_size_of_call_site_table, dw2_output_call_site_table
        callers.  For SECOND section use *C suffixed labels.
        (output_function_exception_table): Call
        output_one_function_exception_table and, when doing hot/cold
        partitioning, also another time for the second section.
        * opts.c: Include except.h.
        (decode_options): Allow -freorder-blocks-and-partition with
        exceptions, unless SJLJ or TARGET_UNWIND_INFO.
        * Makefile.in (opts.o): Depend on $(EXCEPT_H).
        * function.h (struct rtl_eh): Change call_site_record from
        scalar into array of 2 elements.

        * g++.dg/tree-prof/partition1.C: New test.

------- Comment #28 from howarth at nitro dot med dot uc dot edu  2009-10-02 14:08 -------
On reflection, I think the change Mike proposed for darwin.c in Comment 13
fails because it flag_reorder_blocks never gets set to 1 by that patch. I don't
know how I could implement the three variations of setting that which occur in
opts.c from within the overrides of darwin.c. Those cases in opts.c are listed
as...

  /* The optimization to partition hot and cold basic blocks into separate
     sections of the .o and executable files does not work (currently)
     with exception handling.  This is because there is no support for
     generating unwind info.  If flag_exceptions is turned on we need to
     turn off the partitioning optimization.  */

  /* If user requested unwind info, then turn off the partitioning
     optimization.  */

  /* If the target requested unwind info, then turn off the partitioning
     optimization with a different message.  Likewise, if the target does not
     support named sections.  */

Would it be as simple as duplicating those three variations of the conditional
within the overrides of darwin.c to duplicate their behavior? It seem much
better to fix the breakage in opts.c caused by r150553.

Jakub,
   Do you mean that we need to pass 'second' from gcc/ira-int.h?

  /* Allocnos connected by the copy.  The first allocno should have
     smaller order number than the second one.  */
  ira_allocno_t first, second;

to darwin_emit_unwind_label()? Also, what would we use to detect whether the
first and second FDE's came from hot or cold sections?

I suspect the other case is simply:

if (flag_exceptions)
  flag_reorder_blocks_and_partition = 0;

be added, just like the code for flag_unwind_tables.  I suspect this, as the

I'll take a look at perhaps just setting...

flag_reorder_blocks_and_partition = 0;
flag_reorder_blocks = 1;

 in darwin.c's overrides when targeting <10.6 and adjusting
darwin_emit_unwind() to not emit labels when targeting >=10.6.

[Bug c++/41313] r150553 causes g++.dg/tree-prof/partition1.C compilation and execution test failures on *-apple-darwin*

Opps. In both of the last patch...

+  if ((darwin_macosx_version_min && strverscmp(darwin_macosx_version_min,
"10.6") >= 0) || flag_reorder_blocks_and_partition)

should be

+  if (!(darwin_macosx_version_min && strverscmp(darwin_macosx_version_min,
"10.6") >= 0) && flag_reorder_blocks_and_partition)

of course.

Mike,
    Does darwin have named sections? If so, we can drop the check on
!targetm.have_named_sections.
